The very cells that created us may have a role in saving our lives. Scientists have always been amazed by the energy production system in a sperm’s tail. The system drives flagellar movement and is ...

An artistic illustration depicting "Maxwell's demon" modulating the diffusion speed of an enzyme. The demon represents the physical mechanism by which the enzyme uses information to break chemical ...

Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, ...

After a long search, RIKEN researchers have identified an enzyme crucial for keeping lipid-linked sugar chains in check in yeast cells. This finding, published in the Journal of Cell Biology, reveals ...

Living cells are sustained by countless chemical reactions that must be carefully regulated to maintain internal order and function. Enzymes play a ...

Sir2, an enzyme belonging to sirtuins, has been effectively involved in the deacetylation of proteins. A tandem allosteric effect of reactant and product is responsible for the efficient deacetylation ...

A new study shows exercise releases a liver enzyme that repairs aging brain blood vessels and restores memory in mice.

For much of nutrition science history, trace minerals were discussed almost exclusively in the context of deficiency diseases ...

Nicotiana benthamiana plants in a lab at UC Davis. Plants form new branches when a hormone called strigolactone breaks down. UC Davis plant biologists have now defined the enzymes that break down ...

Every year, thousands of tons of brown algae are extracted from the seabed to obtain compounds such as alginates, a polymer composed of sugars that has high density and strength, offering potential ...
